Application filed April 17, 1915. Serial No. 22,012.

zen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Explosive Shells; and I do declare the following to be a full, clean and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in.

projectiles and moreparticularly to explosive bullets or shells The 'ii-iniary object of the invention is to provide a shell or bullet which IS safe for; transportation and storage ]')ll ll OSBS but or highly explosive properties, eiilcient in service} and constructed to cxploi'le after the projectile has penetrated or partially penetrated. the object at which it is directed Another object of the invention is to provide a projectile of this character eqnipped with meansfor destroying: the OlJ]QCt at which it directed by tearing it internally after the projectile has penetrated it.

lVith these and other objects in View, the invention consists of certain novel features of constrmia'i-iom and the COD'llllIlFtlllUll and. arraiwement of parts as will be more fully described and claimed.

In the accompanying drawings: Figure 1 represents a side elevation of a projectile constructed in accordance with this inrention; Fig-,1. P. is a longitiulinal section thereof; Fig. 3 is an enlarged longitudinal section. of the projectile with the cap removed and arranged in juxtaposition ready for as "l is a transverse section taken on. the line -l:---fl of Fig The cartridge con ten'iplateil by the present invention comprises a shell or jacket 1 preferably constructed of steel and having an explosive cap 5: rounded at its rear end and provided at its front end with a reduced tubular extension 3 here shown connected with the bodv portion of the shell by an in clined shoulder 4. i

lelescopically engaged \\ith the tubular extension is the projectile 5 of the cartridge and which is here shown in the form of a cylindrical casing 6 closed at both ends by disk-like caps or closures 7 and which are held in connected relation by means of rods 9 which pass lon 1 nally through the casing and are shown having threaded engagement with the disks 7 and 8, thereby reliably holding them in operative position.

The front plate 8 of the projectile 5 has an exploding cap 10 mounted therein and arranged in front of this cap carrying plate 8 is a lon itudinally extending member 11 having a core 12 in the center thereof to permit the insertion of a pin 13 carried by a soft metal cap 14, said pin being preferably soldered in said cap and here shown pro vided with a head. 15 mounted in the cap and held by the solder therein. The walls of the casing 6 preferably converge toward their free ends and are externally threaded as shown at 16 to receive the threaded cap 14 which when engaged therewith, will cause the free end ofits pin 13 to be disposed adjacent to the cap 10 but spaced therefrom a. suilicient distance to render the explosive perfectly safe for storing" and transportation and which only becomes dangerous when the metal cap forcibly engages some object such as would exert sufficient pressure to force said cap rearwardly a sufficient distance to engage the pin 13 with the exploding cap 10.

The casino 6 of the projectile 5 is filled with an explosive preferably smokeless powder 1 and has embedded therein 1nultiplicity of jagged pieces 17 of steel or other hard material.

The steel jacket or easing 1 is also filled with an explosive material preferably smokeless powder as shown at F.

From the above description, it will be ob YlOlIS that when sufiicient force is brought to bear on the exploding cap 2 such is caused by the firing of a gun the po der 1 in the shell 1 will be exploded and thereby drive out the telescopially engaged projectile 5 mounted in the front end thereof and the tapered rapped end of this member on coming into contact with the object toward which it is directed will have said cap sulliciently flattened, owing to its soft formation so as to cause the pin 13 to be driven inwardly against the exploding: cap 10 and thereby explode the powder P in the casing (l oi said member 5, it being obvious thatu gitudinal open and allowing the pieces 17 to penetrate the beforementionedobject. I I claim as my invention:

1. An explosive of the class described comprising a tubular casing closed at its opposite ends and filled with an explosive, an exploding cap in one of said closures, a forwardly tapering chamber encircling said cap carryin closure and arranged in lonalinement with said casing, said chamber having its outer end threaded, a soft metal cap having threaded engagement with said chamber, said cap tapering toward its free endand having a pin mounted therein and, extending longitudinally rearward With its free end positioned adjacent the explosive cap of said closure when the parts are assembled, and a longitudinally extending member arranged in said chamber, the former having a bore for insertion of said pin whereby toprovide a guide for the same.

2. An explosiveof the class described comprising a tubular casing, a pair of disks closing theopposite ends of said casing, rods secured to said disks for holding them in connected relation, said casing being filled with an explosive having jagged elements embedded therein, an exploding cap in one of said disks, a forwardly tapering chamber arranged in longitudinal alinement with said pm mounted therein and extending longitudinally rearward with its free end positioned adjacent said explosive cap when the parts are assembled.

. 3. An explosive of the prising a'tubular casing closed at its op-.

posite ends and filled with an explosive, an exploding cap in one of said closures, a forwazrdly tapered chamber encircling said cap carrying closure and arranged in longitudinal alinement with said casing, said chamber having its outer end threaded, a soft metal cap having threaded engagement with said chamber, said cap tapering toward'its free end and having a pin mounted therein and extending longitudinally rearward with its free end positioned adjacent theexplosive cap of said closure when the parts are assembled.

' In testimony whereof I have hereunto set my hand in presence oftwo subscribing witnesses.
